Season one of The 100 saw the human race return, after a 97-year exile in space, to a wildly transformed Earth…only to discover that the human race had never truly left. Clarke found herself forced to lead a band of disposable juvenile delinquents as they faced death at every turn – from a world transformed by radiation, from the fierce Grounders who somehow managed to survive in it, and, perhaps worst of all, from themselves.

Alternately challenged and supported by rival leader Bellamy, the two found common purpose: Survival. Through it all, Finn was helplessly drawn to Clarke, destroying his long-standing relationship with the brilliant young mechanic, Raven. Octavia got close to a possible enemy Grounder, Lincoln — some say too close. Meanwhile, as The 100 fought for their lives on the ground, The Ark’s situation was no better. Though Abby believed that The 100 were still alive, she didn’t have proof and couldn’t stop Kane’s population reduction. The killing of 320 volunteers and the subsequent realization that it was in error broke Kane and enflamed a revolution on the Ark that Chancellor Jaha, despite his best efforts, was powerless to stop. Both on the ground and in space, the final episodes will reveal the true desperation of their plight, as our heroes risked everything just to stay alive.

Noble sacrifices and heartbreaking choices changed everyone forever and left them scattered to the wind. The epic second chapter picks up with the newly returned human race desperate to be reunited. Season two’s quest will challenge them beyond anything they have faced before. Hearts will be broken. Lives will be lost. Heroes will be born.
